View detailed information about a service
From the Entity Explorer or the Application Performance Monitoring area overview, click the name of a service to open the service details view. The tabs on the detail view provide detailed insights into your services and their transactions, spans, and errors. See the following sections for information about tabs specific to services. For tabs that display common widgets, such as Health and Alerts, see View entity metric data.
Overview
The right pane of the Overview tab shows the service display name and ID, and other information such as the APM library version, total number of exceptions, Kubernetes cluster and deployment IDs, and creation timestamp.
The service ID is used in defining the service's service key. Editing the display name of the service entity does not affect the service ID or the service key.
The Overview tab also displays the widgets described below.

It also shows additional information, including each instances average response time, average error ratio, and the host where it ran. Use this information to determine if problems associated with a service are affecting only certain instances of the service.
Top 5 Transactions by Total Time
The Top 5 Transactions by Total Time widget shows the five transactions that have the highest total times. For each transaction, the chart lists the total time during the selected time period, the total time for the previous time period, and the percentage of change. Click a transaction name to open the details view for that transaction.
Top 5 Transactions by Error Ratio
The Top 5 Transactions by Error Ratio widget shows the five transactions that have the highest percentage of requests that result in an error. For each transaction, the chart lists the error ratio during the selected time period, the error ratio for the previous time period, and the percentage of change. Click a transaction name to open the details view for that transaction.
Topology map
The topology map displays service instances, remote services, databases, and clusters related to the service. Each entity is color-coded to reflect its health score. Click an entity in the topology map to display high-level information about it in the right pane.
The topology map shows connections for all time periods, not just the selected time period.
The map shows which services are talking to each other, and the arrows indicate whether the communication is inbound or outbound.
Transactions
The Transactions tab lists the transactions that occurred during the selected time period. Each provides shows performance information about the transaction, including the total time, average request rate, average response time, and average error ratio. Click a transaction to view more detailed information.
Traces
The Traces tab displays detailed information about the traces associated with that service during the selected time period. See Traces Explorer for more information.
Insights
On the Insights tab, use the subtabs described below to identify and investigate potential issues. On each tab, click the number below the bar in the Occurrences column to see the traces associated with that interaction during the selected time period. (See Traces Explorer for more information.)
Remote Services
Use information on the Remote Services tab to identify and troubleshoot the remote services calls that consume the most time, including frequent calls and poorly performing calls. Remote services are the outbound endpoints that the selected service connects to. The tab lists both the instrumented and uninstrumented services that were called during the selected time period. Uninstrumented services are gray, and less information is available for them.
Gray text can also indicate that only part of the trace was captured, so some information is not available.
Databases
The Databases tab provides information about the databases that the service interacted with during the specified time period. The graphs at the top show most time consumed per host, database, and query. Use the SQL query table below helps you quickly identify long running queries.
Caches
The Caches tab shows calls to caches that the service made during the specified time period. Use this information to analyze frequent or poorly performing calls.
Exceptions
The Exceptions tab shows information about the exceptions traced for the selected service during the specified time period. When you are troubleshooting a service, use this information to understand the current volume of exceptions, when they started, and which exceptions are most frequent.
Click Exception Class to open the Exception Details pane. Click Last Occurred to view a specific exception in the context of a distributed trace.
Infrastructure
If a service is performing poorly, use the Infrastructure tab to examine the health and performance of related entities. The amount of information available depends on whether the related entity is also monitored by SolarWinds Observability.
By default, the entities on each subtab are displayed in List View, with the available details in columns. On most subtabs, you can also select the following views:
